Toddler Talk in ASL (American Sign Language) at age 1 and month 4: asking for help, signing "thank-you", saluting, faking a cough, attempting to fingerspell #MAMA", "#VP, and "#FOOT", and expanding vocabulary.
Deaf-gain. Where there is a "loss" (from a hearing perspective), there is indeed a gain (from an eyeing perspective). Studies show gains as a result of 'deafness'. For example, a cerebral region of the brain used for hearing in hearing people's brains is not simply unused in deaf people's brains. They are activated with different purposes other than hearing (e.g. touch and visual). In the end, there is no loss.
The toddler "Juli" acquired ASL vocabulary further and developed two-word utterances in ASL. In this video, she answered wh-questions, requested for another, talked with her grandparents via videophone, signed so cute and more.
The video clip shows a toddler at age 1, month 3, making requests, expressing manners "thank-you" and "please", asking for help using the ASL word "help", uttering an emerging two-word utterance... and even signing her own signed name!
